Nice colorful original box. Looks complete with paperwork. Condition: (Very Good – Excellent) Item Dimensions: Box: 15″ x 2″ x 7 – 1/4. The Revell XSL-01 kit has thus become a “Holy Grail” collector’s items that command top dollar. Revell’s conceptual XSL-01. (Experimental Space Laboratory) represented a transitional stage between the romantic “cigar with wings” post-War aesthetic still visible in Hawk’s “Atlas ICBM” and the more utilitarian form that actual launch vehicles had, by this date, already assumed. FINDING A 1957 ORIGINAL LIKE THIS AT A GOOD PRICE IS NEARLY IMPOSSIBLE.
